Let's divide 35212013 by 306
The aim is to understand the frequency of 306 in 35212013.

Let's proceed to step 1:
306 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 306

Advancing to step 2:
If we divide 35 by 306, we get 0 and a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Take the next digit (2) from the dividend and append it to 35, then repeat: 352 / 306

Step 3:
352 divided by 306 is 1 with a remainder of 46.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 306 from 352, we get 46.
Include the next digit (1) from the dividend after 46, then repeat: 461 / 306

On to step 4:
If we divide 461 by 306, we get 1 and a remainder of 155.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 306 from 461 leaves us with 155.
Bring next digit (2) of the dividend behind the 155 and repeat the process: 1552 / 306

Going ahead to step 5:
306 can be fit into 1552 5 times, resulting in a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 115.0
Subtracting 1530 from 1552 leaves us with 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 306

On to step 6:
220 divided by 306 is 0 with a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 1150.0
Subtract 0 from 220 to get 220.
Take the next digit (1) from the dividend and append it to 220, then repeat: 2201 / 306

Going ahead to step 7:
When dividing 2201 by 306, we get 7 with a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 11507.0
If we take 2142 away from 2201, we end up with 59.
Append the next digit (3) from the dividend to 59 and continue with: 593 / 306

Step 8:
If we divide 593 by 306, we get 1 and a remainder of 287.
The next digit of our result is 1. 
Result so far: 115071.0
Deduct 306 from 593 and we're left with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Moving on to step 9:
The number 306 fits into 2870 9 times, leaving a remainder of 116.
Record the quotient 9 as the next digit in the result. 
Result so far: 115071.9
If we take 2754 away from 2870, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 10:
The number 306 fits into 1160 3 times, leaving a remainder of 242.
Put 3 as the next digit of the answer. 
Result so far: 115071.93
If we subtract 918 from 1160, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 11:
306 goes into 2420 7 times with a remainder of 278.
The next digit of our result is 7. 
Result so far: 115071.937
If we subtract 2142 from 2420, we get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Going ahead to step 12:
306 can be fit into 2780 9 times, resulting in a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 115071.9379
Subtracting 2754 from 2780 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 13:
When dividing 260 by 306, we get 0 with a remainder of 260.
Use 0 as the next digit of our solution. 
Result so far: 115071.9379
If we take 0 away from 260, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 14:
306 goes into 2600 8 times with a remainder of 152.
Use 8 as the next digit of our solution. 
Result so far: 115071.937908
If we subtract 2448 from 2600, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 15:
The number 306 fits into 1520 4 times, leaving a remainder of 296.
The next digit of our result is 4. 
Result so far: 115071.9379084
The remainder is 296 after subtracting 1224 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Step 16:
2960 divided by 306 is 9 with a remainder of 206.
The next digit of our result is 9. 
Result so far: 115071.93790849
Subtract 2754 from 2960 to get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

In conclusion, the division gives 115071.93790849 with a balance of 2.06e-07.
